Description

Technical Field

[0001] The utility model relates to the field of geological survey, in particular to a sampling device used for deep geological survey. Background Art

[0002] Sampling in deep geological surveys has multiple purposes, including detecting underground mineral resources such as metal ores, non-metallic ores, coal, oil and natural gas, and assessing their reserves and mining value. Deep geological surveys can also understand the type, distribution, structure and texture of underground rocks, and provide data for the study of geological structure and plate movement.

[0003] After searching, Chinese patent announcement number: CN220454891U discloses a sampling device for deep geological survey. When the drilling rod group loosens the soil layer at the specified position, the rotating shaft removes the drilling rod group and connects the sampling rod group to the rotating shaft. When the sampling drill bit penetrates the soil layer at the specified depth, the sampling drill bit is rotated in the opposite direction of the unidirectional sampling barrel. After the soil sample enters the sampling drill bit from the barrel mouth of the unidirectional sampling barrel, the rotation is stopped, the sampling rod group is taken out, the sampling rod is removed, and the soil sample is taken out from the sample extraction hole, realizing the functions of deep geological survey and sampling.

[0004] In the above technical solution, a sampling drill is used to sample samples in a single rotation direction, and finally the samples are taken out through the sample extraction hole of the sampling drill. However, when sampling, the samples need to be manually poured out from the sampling drill. When a large number of samples are taken in different areas, the physical strength of the sampling personnel is limited and it is impossible to ensure that the samples are completely taken out, so that the residual samples in the sampling drill reduce the subsequent survey effect. Therefore, a sampling device for deep geological survey is proposed to solve the above problems. Utility Model Content
